CAN BRACKET AND HANGER.

Application led July 3, 1924. Serial No. 724,071.

To all whom. t may concern:

Be it known that I, ROBERT F. IjiNDsAY, Sr., a citizen of the UnitedStates, residing at Greenville, in the county of Greenville Y 5 andState of South Carolina, have invented a new and useful Can Bracket andHanger, of which the following is a specification.

This invention relates to a can bracket and hanger, especially adaptedfor use in with a device for agitating liquids by means of air whilethey are being frozen.

In manufacturing ice from raw water it is customary to agitate the waterby means 15 of air introduced through a perforated tube suspended inthecentral part o`f the can in order to remove impurities therefrom, and toprevent the same from being frozen into the ice as it is progressivelyformed from the 20 walls of the can toward its center.

The object of the present invention is generally to improve thelconstruction of the supporting bracket and the connectionof the tubetherewith, so that the bracket is proper position, and the tube has aloa-tingsupport wherebyit may automatically adjust-itself to cans ofdifferent width, and to the space occupied by the core of unfrozen watertherein. The inven- 30 tion also includes a bracket adapted to be of thedifferent types of cans regardless of the distance of the lifting holesfrom the top of the rim, and it does not matter whether the cans have alifting holes in the middle, or a can with ribs in the middle and thelifting holes at one side thereof. Another feature of the invention isan improved arrangement of the perforations in `whereby its function isperformed more uniformly and more efficiently. The specific improvementsby .means 4of lWhich the above and other -desired results are obtainedwill be more fully explained in accompanying drawings which illustratethe invention in its preferred form.

In the drawings: Figure 1 is a vertical longitudinal section easilyattached to any D150 through an ice can, showing the invention inposition.

Figure 2 is a vertical section taken at right angles to Figure 1.

Figure 7 is a sectional view on an entlarged scale of a modified form ofthe invenion.

Figure 8 is a detail view ofthe attaching yoke with a single prong dog.

Figure 9 is a plan view of the attaching bracket shown in Figure 7.

In the drawingsthere is shown an ice can 10, of conventional shape,disposed beneath a rectangular wooden frame 11, and containing apartially frozen block of ice 12, having an unfrozen core of vwater 13.A n air lateral 14 is disposed along one side of the frame 11, which hasa portion cut away, as shown at 15, to provide space for one or moredepending valves 15, each provided with a nipple for attaching one endof an air hose 16. r,The other end of the hose is connected with anozzle 17, having an angular tapered end adapted to seat within theupper end of the tube 18.

The tube 18 is provided with a substan-` tially rectangular head 19 intowhich the upper end-of the tube is expanded, and this head is adapted tot and move freely within a channel shaped bar or support 20, whichextendsacross the upper end of the can, as shown in Fi res 2, 3 and 4.The bar 20 has an elongate opening 21 through which the tube is passed.'Ihe head 19 is of greater length and width than the opening 21. The baris formed at its ends into yokes 22 and supported from the rim of thecan. One of the yokes .22 is preferably formed with hook-shaped ngers 24adapted to receive the rim of the can, while the other yoke 23 isprovided with horizontal fingers 25 ada ted to rest upon the rim at theopposite sidle of the can, thus allowing the hangr o to becapplied tocans varying considera in width; A lug 26 is pivoted within each end ofthe channel bar 20, and is ada ted to extend outwardly between the armso? the yoke into engagement with the adjacent lift-- ing hole 27,usually formed at the upper end of the can midway between the edgesthereof.

If the can is provided with a central rib and i the lifting hole islocated at one side thereof, the lug 26 may be folded inwardly into thechannel bar 2O where it is out of the way. Dogs, 28 and 29 are pivotedwithin the channel bar 20 at opposite sides of its center and extendupwardly and outwardly above and beyond the rim of the can, one ofthedogs being provided with a single prong 30, and the other dog beingprovided with two prongs, as shown at 31, which prongs are adapted toengage the inner faces of' the wooden frame 11, so as to hold down thecan and also prevent it from becoming laterally displaced. Each of thedogs 28 and 29 is extended upwardly and inwardly from its ypivot to forma head or linger piece 32, by means of which it may be easily disengagedfrom the frame when the ice is to be harvested.

The tube 18 is provided with a plurality of holes 33, equally spaced andarranged alternately on opposite sides of the tube, and progressivelydecreasing in diameter from the bottom to the top of the tube.

In the modification shown in Figures 7 and 9, .I have shown a channelbar 20, which differs from the channel bar 20 in that it extends onlypart way across the can and is supported entirely from the yoke 22 withhook-shaped fingers 24, the do 29 1n with the double prongs 3l being`use being denser than vbe seen that l have connectiontherewith.I Abrace 34 secured to the under side of the channel bar 20 engages theinner face of the can. The construction is in other respects similar tothat shown in the other gures. l

From the foregoin description, it will evised a can bracket and hanger iwhich fits every type of can used for making artificial ice. In using itin connection with a can havingvplain Sides with lifting holes in thecenter, the lugs 26 determine the position of the bracket centrally ofthe can, and owing to their pivotal connections they will fit into thelift ing holes 'at diferent distances from the to of the rim.y In theevent that the can 1s ribbed in the center and the lifting hole at oneside of the rib, the centering lug is thrown back into the channel ofthe bar, and the arms of the yoke fit the rib to center the bracket. Thedogs 28 and 29 automatically engagev the inner faces of the wooden frameas soon as the bracket is attached, and positively hold the, can inposition at the bottom of the brine, which, the fresh water in the can,has a tendency to buoy up the can. A11- other object of the holding downdevice is that the can is held level, and the topof the block of ice isconsequently made level and uniform, whereas in the absence of somemeans for positively holding the can, it is liable to tilt and to resultIin an uneven or slanting top, making the -block inconven- `the sidesofient to store, and making it impossible to cut it uniformly.

The channel shape of the bar 20 makes it strong and durable, and alsoforms a guideway for the head of the tube which has a oating support.rllhe elongated slot 21' permits a range of movement suiicient to allowthe tube to -adjust itself to cans of different width. It will alsocompensate forbent or distorted walls. vantage 'of this floating tube isthat when the brine circulation is greater on one side of the can thanon the other, so that transfer of heat is more rapid on one side, andthe ice freezes faster on that side, the float-- ing tube agitated bythe discharge of air automatically nds the center of the unfrozen zone,in other words, the unfrozen core, and when the two walls have frozentogether and have met. the tube will be at the meeting point. Thus, theblock of ice when completed is clear throughout and has no core. Inprior constructions where the tube is pivotally connected port' it isconfined in its swinging movement to a single vertical plane. In thepresent invention the tube swings slightly out of a single plane,traversing a double elliptical area or describes in its motion thefigure 8, which causes the tube'to strike different parts of the icewalls and prevents it from sticking and freezing in before the ice cakecloses up. This result is due to the head 19 at the top of the tube inconnection with the elongated slot 21 in which the tube is caused toswing.

The bracket and hanger are very easily applied to the can, and just aseasily removed. The shape of the yokes provides a wide Abearing surface,`and yet there is plenty vof room -at the center of the can to removethe core and to refill without disturbing the hanger or tube. At harvesttime, however, it is only necessary to press the headsj32 of the dogsdown into .the channel to release them from Ythe framework, so that thehanger or bracket is easily lifted out.

L'lhe size and arrangement of the holes 33 is also an important feature.These holes are arranged at equal distances from each other, andalternately on opposite sides of the tube. Each hplc is slightly less in(liameter than the one below it.' In practice, I have rovided fourholes, ranging in diameter from .04 inch down to -.027 inch in diameter,but, of course, the number` and absolute sizes of the holes may ,bevaried. By this arrangement, the air, der the least pressure, passesthrough the greatest hole, and the distribution of the air is moreuniform and'results in a more ecient operation than is possible 'withtubes as heretoforeconstructed.

While the construction of the bracket and to the supl which is unhangeras' herein described Iis to be prefered, 'it is, of course, apparent.that various modifications may be made in the details thereof withoutdeparting fromthe salient Ifeatures of the invention, which it is mypurpose to cover in the appended claims.

connecting theV tube to the support and ymeans for causing lateralswinging movement slightly out of a single vertical plane sothat thetube traverses a double elliptical area which causes the tube to strikedifferent the tub partsof the ice walls, said connecting means alsoallowing the tube to rise automatically away from the support.
